Mobx: Is there any costs for calling observable on already observed value?

[Niryo]

let obj1 = observable({bla: true});
let obj2 = observable(obj1);

will it introduce any performance issue or is it safe to do it?
will changes to obj2 trigger only one render?

I believe this answers your question ;)

https://github.com/mobxjs/mobx/blob/326eae873af8c675202c4f47ed7d86b1e6107b4a/src/v5/api/observable.ts#L87

Sometimes quick peek into lib source code is faster than asking somewhere ;)
